Floribunda rose plant named &#39;hadcup&#39;

ABSTRACT

A new and distinct rose cultivar of the Florabunda class characterized by having long lasting clusters of deep yellow flowers on clean stems without prickles and having a rapid rebloom cycle. The plant is upright and bushy and is of medium height, generally averaging about 1 meter. Stems are well covered with matte foliage. The plant is resistant to mildew, rust and blackspot. The generic name of this plant is designated as ‘HADCUP’. It is being marketed under the commercial name of ‘SMOOTH BUTTERCUP’.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Floribunda Rose Plant

The present invention relates to a new and distinctive cultivar of roseplant of the Floribunda class, which was originated by my crossing‘Kika’ as the seed parent with the unamed seedling ((BasildonBond×Arthur Bell)×Midas Touch)) as the pollen parent.

Among the novel characteristics possessed by the new cultivar whichdistinguish it from:

(a) All other cultivars of which I am aware are:

-   -   (1) Prickles are absent from any stems.    -   (2) Deep yellow flowers.    -   (3) Flowers in clusters of 3 to 14 blooms.    -   (4) Very consistent free bloomer.

(b) Seed parent: White hybrid tea, few prickles.

Pollen parent: Medium yellow floribunda with prickles.

Asexual reproduction of the new rose cultivar by budding onto therootstock ‘Dr. Huey’, as performed at Wasco. Calif., shows that theaforementioned and all other distinctive characteristics come true toform and are established and transmitted through succeedingpropagations.

The accompanying drawing shows typical specimens of the vegetativegrowth and flowers of the new cultivar in different stages ofdevelopment and as depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with colorterminology in accordance with The Royal Horticultural Society ColourChart (RHSCC). The terminology used in the color description hereinrefers to plate numbers in the aforementioned color chart, e.g. ‘YellowGroup 16A’ in Fan 1 of The Royal Horticultural Society Colour Chart.

-   Parentage:    -   -   Seed parent.—IRAR registered: ‘Ortkee’; commercial name:            ‘Kika’; U.S. Plant patent — None.        -   Pollen parent.—Seedling — ((Basildon Bond×Arthur Bell)×Midas            Touch)).-   Class: Hybrid Tea.
